INSTALLATION INSTALLATION MOUNT HEIGHTS DUCTING Minimum mount height between range top to hood bottom should be no less than 24". FIRE HAZARD 12" Maximum mount height should be no higher than 32". NEVER exhaust air or terminate duct work into spaces between walls, crawl spaces, ceiling,attics or garages. All exhaust must be ducted to the outside. 18" Min 24"-Max 32" 96" It is important to install the hood at the proper mounting height. Hoods mounted too low could result in heat damage and fire hazard; while hoods mounted too high will be hard to reach and will loose its performance and efficiency. Use metal ductwork only. Fasten all connections with sheet metal screws and tape all joints w/ certified Silver Tape or Duct Tape. Some Ducting Options: If available, also refer range manufacturer's height clearance requirements and recommended hood mounting height above range. 36" Side wall cap w/ gravity damper Side wall cap w/ gravity damper DUCTING A minimum of 8" round duct must be used to maintain maximum air flow efficiency. Minimum Duct Size: Round: 8" minimum Soffit or crawl space Always use rigid type metal ducts only. Flexible ducts could restrict air flow by up to 50%. Also use calculation (on right) to compute total available duct run when using elbows, transitions and caps. ALWAYS, when possible, reduce the number or transitions and turns. If long duct run is required, increase duct size from 8" to 9 or 10". If a reducer is used, install a long reducer instead of a pancake reducer. Reduce duct size as far away from opening as possible. If turns or transitions are required: Install as far away from opening and as far apart, between 2, as possible. Duct Run Calculation: Maximum run 8" Deduct: each 90 Elbow used each 45 elbow used each 8" transition used each 3/14 x 10" to 8" each 3/14 x 10" to 8" transition used Side Wall Cap w/ damper Roof Cap 100 FT 15 FT 9 FT 1 FT 5 FT 30 FT 30 FT e.g.- 1 roof cap, 2x90 elbows, 1 x 45 elbow used: =30' + 30' + 9' =69' used, 31' available for straight duct runs.

MOUNTING THE RANGEHOOD INSTALLATION 1. Begin by determining hood mounting height on wall. MOUNTING THE RANGEHOOD INSTALLATION 5. Install electrical. 6. Install duct work and tape all joints. 7. Power up hood and check for leaks around duct joints, and if necessary apply more duct tape. duct/silver tape 2. Level and mount the wood panel onto the wall at the appropriate height and secure it to the studs. This wood panel should be 1/2" x 3" and the width will either be 29", 35" or 47" depending on the width of the hood. Measure the distance between the wall mounting brackets and fasten them onto the wood panel. Refer to the diagram for how the brackets attach to the panel. Make sure they will line up with the tabs on the back of the hood. Lift the hood and hang it onto the brackets. 3. Temporarily remove the baffle filters from hood, and level hood by adjusting the metal brackets located inside of the hood. (Note: there is approximately 1/2 total adjustability up and down). These brackets are adjusted by a screw that can be easily turned with your fingers. There is one on each side on the inside back wall of the hood. After ensuring that the hood is level, complete ly tighten the screws to secure the hood to the wall. 4. Optional: After the hood is attached to the mounting brackets, you may further secure it by screwing two screws into the wall from the inside of the hood. You will need to drill through the back wall of the hood to do so. 8. Install optional duct cover and/or backsplash. Note that the duct cover and backsplash are sold separately. 9.
